making the robot work with 4 ir object/detection avoidance setup

i build a robot with 4 infrared object detection components instead of the two that the roboticsv2 manual shows. For a program i used the one below which is page 252-253 on the roboticv2 manual. I thought by adding two more freqout and irDetects it would work but it does not. What am i doing wrong guys?

thanks in advance!

    wow [noparse]:)[/noparse] too messy.
    You should use the template Jon always mention, and it is really usefull to avoid easy bugs.

    A quick look at :
    FREQOUT 8, 1, 38500 ' Check IR Detectors
    irDetectLeft = IN9
     
    FREQOUT 5,1,38500       'I added this
    [b]irDetectleft=IN6[/b]
    FREQOUT 2, 1, 38500
    irDetectRight = IN0
     
    FFREQOUT 14,1,38500    'I added this
    [b]irDetectleft=IN15[/b]
    



    well, sounds like the same irDetectleft variable is used for two differents sensors readings on pin 6 and 15...
    You should create as many variables as IR sensors to hold the values and change the truth table of the decision process (' Decide how to navigate.') to take into accont the new variables.
